Problems solved by technology

Using biological enzymes to degrade polysaccharides is an effective way, but the traditional method is to spray a thin layer of enzyme solution on the material to be processed or add the enzyme solution to the slurry of the material to be processed. One method limits the speed of processing, and the latter method is because the cells are saturated with water, the enzyme solution can only slowly diffuse into the intercellular space, and the conversion rate is too low
However, there are few reports on the biodegradation technology of mannan in palm (kernel) meal. It is difficult to control the preparation of the enzyme solution used for degradation and the temperature and time of the enzymatic hydrolysis reaction

Embodiment 1

[0022] The palm kernel meal with a moisture content of 18.42% was put into a drier for drying. During drying, the temperature was controlled at about 100° C., the drying time was set at 40 minutes, and the moisture content after drying was determined to be 4.47%. Two samples of 180.0 g of palm kernel meal were weighed, and 200 ml of an enzyme solution containing mannanase (pH value 5.3) was added to each sample, and transferred to two stoppered reaction tubes respectively. Then weigh 180.0 g of palm kernel meal as the third sample, add 200 ml of aqueous buffer solution containing sodium citrate (pH value is 5.3), and transfer to another stoppered reaction tube. The first sample was immediately mixed with 1000ml of aqueous buffer containing sodium citrate (pH 5.3), filtered through a filter, and the insoluble matter was washed with 1000ml of aqueous buffer containing sodium citrate (pH 5.3), and the insoluble After drying the product at 100° C. for 24 hours, the weight of the d...

Embodiment 2

[0026] Get 160Kg of dried palm kernel meal in Example 1, mix it with 340Kg of aqueous buffer containing sodium acetate (pH value is 5.2), and transfer to the reactor. Another 160Kg sample was taken, and 340Kg of an enzyme solution (pH value 5.2) containing mannanase was added to the sample, and transferred to the reaction kettle. Wherein 340Kg of the enzyme solution containing mannanase is prepared by mixing 1.6Kg of Trichoderma reesei (Trichoderma reesei) with 340Kg of sodium acetate buffer solution (pH value is 5.2), which can produce about 160 ~3.2 million units of mannanase. The above two samples were simultaneously placed in a spraying device with a temperature of 62°C±0.1°C and incubated for 42 hours with shaking to obtain the product.

[0027] Take 10g of the solution from each of the above two reaction kettles and place them in test tubes for analysis, and the remaining products are dried and pulverized for feeding experiments on animals such as laying ducks. Add 20m...

Embodiment 3

[0030] The palm meal with a moisture content of 17.5% is put into a drier for drying, the temperature is controlled at about 95°C during drying, the drying time is set at 50 minutes, and the moisture content after drying is determined to be 4.25%. A 160.0 g sample of palm meal was weighed, mixed with 340 ml of aqueous buffer containing sodium acetate (pH 5.2), and transferred to a stoppered reaction tube. A second 160 g sample was weighed, 200 ml of an enzyme solution (pH 5.3) containing mannanase was added / added to this sample, and transferred to a stoppered reaction tube. 200ml of the enzyme solution containing mannanase is prepared by mixing 1.63g of Trichoderma reesei with 200ml of sodium citrate (50mmol) buffer solution, which can produce about 1630-3260 units of mannanase. The above two samples were simultaneously placed in an automatic temperature-adjusting incubator at 10 rpm, the temperature was set at 55°C±0.5°C, and incubated for 30 hours to obtain the product.

Abstract

The invention relates a method for degrading palm meal and palm kernel meal by using an enzyme. The method mainly comprises the steps of mixing dry palm meal and / or palm kernel meal with enzyme solution containing mannase, placing the mixed materials at a temperature of 40-100 DEG C for zymohydrolysis, and manufacturing finished products after 4-80 hours, wherein the use level of the mannase for the dry palm meal and / or the palm kernel meal per gram is 5-120 units, the pH value of the enzyme solution is kept between 2-11, and the moisture content of the mixed materials is kept between 30-70%. Through the processing method in the invention, no large quantities of waste is produced, and the product has the advantages of higher nutritional value, simple and easy process, low cost, and good product stability. The processed product can be used as animal feed instead of corn and bean pulp.

Description

technical field [0001] The invention relates to a method for degrading palm dregs and palm kernel dregs by using biological enzymes, through which a mixture that can be used as feed or feed formula can be obtained. Background technique [0002] Palm meal and palm kernel meal are residues produced during the process of extracting palm pulp and palm kernel respectively. They have high crude fiber content, low crude protein content (14-19%), lysine, methionine and Tryptophan is lacking, and fatty acid belongs to saturated fatty acid (see Table 1 for main component analysis). Palm (kernel) meal belongs to roughage, because of its low price, no mold, and no side effects, it is especially suitable for feeding ruminants, such as cattle, sheep, deer, etc. [0003] Table 1: Analysis of main components of palm (kernel) meal [0004] ingredients content Protein ≥14% Fat (Oil) ≥8% Moisture ≤9.5% Impurities (Dirt & Shell) ...
